Google search for 'tcp header' found this first:
http://www.freesoft.org/CIE/Course/Section4/8.htm
Assuming that is really the start of the header, 06C2 corresponds to
1730 in decimal. And so on. If you're good at hex->bin->decimal, you
can do it. But it's not easy for humans to glance at this and makes
sense of it. Each 4 hex characters is 16 bits, so you can match up
blocks, but that only gets you so far.
